I dunno how to do 2 maths problem sum.?

Question

Here's the questions:
1. Suanne had 4 cakes and Barry had 12 cakes. They cut the cakes into equal pieces. They then distributed the cakes equally among 5 pupils. How many cakes did each pupil get?
2. Mei Lan had 5 identical pieces of paper. She cut each piece into 3 identical rectangles. She then distributed the rectangular pieces of paper equally among 6 pupils. How many rectangular pieces of paper did each pupil get?
I appreciate everyone's help.=)

Answer 1

1)4+12=16.
16 divide by 5 = 3.2

2) 5 x3= 15
15 divide by 6= 2.5

Answer 2

1 total no of cakes=12+4=16.... if each of the 16 cakes is equally cut into 5 pieces den total no of pieces of cake =80
80 pieces is divided into 5 students then each person will recieve 16 pieces if 5 pieces make a cake then each student recieved 3cakes and 1/5 of a cake(i.e, 1 piece)
2 5 identical papers each cut into 3
then total no=15
distributed among 6 then each get 2 and 1/2 rectangles

Answer 3

4 +12=16/5=3 1/5 cakes apiece or 3 cakes and 1 left over
5 x 3=15/6= 2 1/2 rectangular pieces each or 2 whole and 3 left over

Answer 4

1.
4 cakes + 12 cakes = 16 cakes
Suasanne and Barry had 16 cakes altogether

16 cakes divided by 5 students = 3.2 or 3 1/5 cakes
Each pupil got 3.2 or 3 1/5 cakes.

2.
5 pieces of paper divided by 3 pieces = 15 pieces of paper
15 pieces of paper divided by 6 students = 2 pieces with 3 remainder (since she cut the paper pre-distribution and it does not mention her cutting the paper again)

Answer 5

1. altogether, there are 4+12, which is 16 cake.
distributed equally among 5 pupils is 16/5=3 1/5
therefore, each pupil got 3 1/5 cake

2. altogether, there will be 5x3 rectangular pieces, which is 15 pieces.
distributed equally among 6 pupils is 15/6=2 1/2

hope it has helped you

Answer 6

your equations are: x-3y = -4 and 2x + 6y = 5. get the fee of y from the first equation- y = ( x + 4)/3 then change this to the 2d equation, 2x + 6 ( x + 4) / 3 = 5 2x + 2 ( x + 4) = 5 x = - 3/4 , then change this fee to the y equation, this may yield y = 13/12 0r a million and a million/12.
